Does Drinking Tea Cause Kidney Stones Tea Effects On Renal Health

Tea is a big NO for those who suffer from kidney stones. This is because tea has very high oxalate content and oxalic acid aid in the forming of kidney stones. So, does tea cause kidney stones? The answer is yes, drinking too much tea can lead to the formation of kidney stones. However, recent studies prove that green tea may be consumed by those who suffer from kidney stones as it contains a compound that prevents kidney stones from being formed.

Can You Get Kidney Stones From Drinking Tea

Some true teas from the Camellia sinensis plant are relatively high in oxalates, which naturally leads to concerns that they could contribute to kidney stone formation.

While public opinions from urologists and other experts may fall on both sides of this issue, peer-reviewed research is more conclusive.

Scientific studies find a risk of kidney stones in tea drinkers compared to people who dont drink tea.

A 2013 analysis of over 194,000 participants found that there was an inverse relationship between daily intake of tea and the risk of new kidney stone formation.

Also, the effect was cumulativethe more cups of tea per day and per week, the greater the benefit. That said, a relationship in study data doesnt prove causation, and theres also a possibility that people who drink tea also eat a healthier overall diet .

A 2019 study also found that drinking green tea daily did not raise the risk of stone formation.

And a fascinating 2009 study found that oxalate crystals formed in the presence of green tea were flatter and more fragile than those formed under regular conditions, which the authors argued could prevent the formation of clinical kidney stones.

On the other side of the fence, Dr. John Milner, an assistant professor at the Department of Urology at Loyola University claims that For people who have a tendency to form the most common type of kidney stones, iced tea is one of the worst things to drink.

Excessive Ice Tea Leads To Mans Kidney Failure

Does Iced Tea Cause Kidney Stones?

A manâs kidney failure has been linked to his excessive iced tea habitbut donât worry, youâre probably not approaching the danger zone. The 56-year-old Arkansas man was drinking 16 glasses of the stuff daily, amounting to a gallon every day,the AP reports. Black tea contains a lot of a compound called oxalate, which can lead to kidney issues,LiveScience reports.

âWith 16 cups of tea daily, the patientâs daily consumption of oxalate was more than 1500mga level that is higher than the average American intake by a factor of approximately three to 10,â scientists say.

The man was hospitalized last year, and his urine contained lots of the calcium oxalate crystals involved in kidney stones. He was put on dialysis and he may be on it for life, doctors note.

âWe are not advising against tea consumption,â a researcher says. âIf you are healthy and drink tea with moderation, it should not cause damage to your kidneys.â

In fact, past studies have suggested that a more reasonable amount of tea can actually fight kidney stones, an outside researcher tells Reuters. Still, many of us apparently consume too much oxalate, which can be found in spinach, chocolate, nuts, and wheat bran, among other foods. While experts donât recommend going beyond 50mg per day, the average American consumes 152mg to 511mg, researchers note.

Does Iced Tea Cause Kidney Stones

Iced tea in the summer is one of the most relaxing and refreshing drinks. However, the fact that iced tea can lead to kidney stones makes it a slightly less enjoyable drink. Doctors have found that a chemical in oxalate that is found in iced tea is a key chemical that helps form kidney stones.

John Milner, an urologist at Loyola University Medical Center, said that people who drink a lot of iced tea are more in danger of developing kidney stones. However, being dehydrated also causes them. Men the age of 40 or older are four times more likely to develop kidney stones than women. A study was done on a 56 year old man who experienced kidney failure. After doctors found oxalate minerals, they found out the man was drinking about 16 glasses of iced tea per day. Although the doctors could not find the causation between the two, they know that they are correlated. As the amount of iced tea consumed increases, the higher the chance of developing kidney stones. Doctors tend to put kidney stone patients on diets with low-oxalate consumption. In her article on Health Day, Kathleen Doheny states, the recommended intake of oxalate per day is 40-50 milligrams, yet Americans tend to intake 50-100 milligrams. Americans that are in more danger of kidney stones should drink less iced tea and consume less oxalate.

Infrequently Asked Questions: Can Drinking Too Much Tea Cause Kidney Stones

The world is full of questions we all want answers to but are either too embarrassed, time-crunched or intimidated to actually ask. In the spirit of that shared experience, we’ve embarked on a journey to answer all of the questions that burn in the minds of Philadelphians — everything from universal curiosities to Philly-specific musings .

Tea drinkers have long feared the answer to the question of whether their hydration method of choice is actually detrimental to their kidney health. Eager to set the record straight, we reached out to Dr. Pooja Singh, a clinical assistant professor in nephrology at Jefferson University Hospital.

Getting to the chase, can drinking too much tea really cause kidney stones?

The answer to that is ‘Yes,’ but only if it is done in an excess amount. And the reason for that is because tea, specifically black tea, which is how we drink tea in America, is very rich in a mineral called oxalates. These are present not only in black tea, but chocolates, spinach, beets and peanuts. So if you have susceptibility for stones you and I, if we are not susceptible to kidney stones, we can perhaps drink a lot more and not have a problem …

Is oxalate present in other teas, too?

Specifically if they have a history, not to drink so much black tea. And it also goes with other things like the chocolate and the spinach and other things I mentioned.

How To Avoid Kidney Stones

Dr. Hammontree discussing ice tea effects of Kidney stones

Here are the five ways to help prevent kidney stones:

Drink plenty of water: Drinking extra water dilutes the substances in urine that lead to stones. Strive to drink enough fluids to pass 2 liters of urine a day, which is roughly eight standard 8-ounce cups. It may help to include some citrus beverages, like lemonade and orange juice. The citrate in these beverages helps block stone formation.

Eat calcium rich foods: Dietary calcium binds to oxalate in your intestines and thereby decreases the amount of oxalate that gets absorbed into the bloodstream and then excreted by the kidney. This lowers the concentration of oxalate in the urine, so there is less chance it can bind to urinary calcium. That leads to decreased risk of kidney stones.

Reduce sodium: A high-sodium diet can trigger kidney stones because it increases the amount of calcium in your urine. So, a low-sodium diet is recommended for the stone prone. Current guidelines suggest limiting total daily sodium intake to 2,300 mg. If sodium has contributed to kidney stones in the past, try to reduce your daily intake to 1,500 mg. This will also be good for your blood pressure and heart.

Avoid stone-forming foods: Beets, chocolate, spinach, rhubarb, tea, and most nuts are rich in oxalate, which can contribute to kidney stones. If you suffer from stones, your doctor may advise you to avoid these foods or to consume them in smaller amounts.

    What Is The Relationship Between Green Tea And Kidney Stones

    Green tea has actually been shown to reduce the risk of kidney stone formation in women by a respectable eight percent. In men, that risk reduction increases to 14 percent. While green tea still leads to an increase of oxalate in the blood, it adversely impacts crystal formation, which is the kidney stone.

    How Does Green Tea Help Prevent Kidney Stones?

    It is believed that the extract from green tea ends up adhering itself to the calcium oxalate as it is emitted. This impacts the way that the crystals are formed in comparison to other types of tea. In essence, the crystals formed from green tea do not clump together like they normally would.

    How Do Oxalates Threaten My Kidney Health

    Oxalates occur naturally in many foods. The kidneys job is to clean these waste products from the blood, that then leave the body in the urine.

    If there is too little liquid in the urine and too much oxalate, calcium oxalate fragments can occur. As these fragments build up, crystals accumulate and stones can be created.

    The simple thought is that food and beverages with higher oxalate levels are linked to higher risk of kidney stones.

    However recent research is showing that tea, specifically may contain substances that actually repair and protect or kidney from oxalic-acid damage.

    How Green Tea Prevents Formation Of Kidney Stones

    The extracts from green tea get bonded to calcium oxalate and the resulting crystalline takes a different shape, which prevents it from clumping together and forming kidney stones. The small crystals pass easily through urine. As per the study, the more green tea causes the calcium oxalate crystals to become flat and flatter crystals forms kidney stones that are less stable, which break up easily.

    Research on the subject is still ongoing, though the findings thus far seem to indicate that green tea isnt as bad for the kidneys as it was previously thought to be. But it should only be consumed after consultation with a renal specialist.

    How Much Tea Is Too Much

    Kidney stone prevention, Tea drinking, America Now Dr. Lee Hammontree

    Most herbal and green teas are safe to consume in larger amounts, however you may want to be more conservative if drinking darker, fermented teas such as black tea or puerh.

    Black can still be beneficial in moderate amounts. A 2002 study in the Journal of Epidemiology found that 8 oz of tea consumed daily actually reduced the risk of stone formation by 14% .

    Moderation is key when consuming tea. A recent case study from the Central Arkansas Veterans Healthcare System described a patient that had drank 16, 8 ounce glasses of iced tea daily and had to be put on dialysis because his kidneys had stopped functioning .
